摘要： A digital multilevel memory system includes a charge pump and a voltage regulator for generating regulated high voltages for various memory operations. The charge pump may include a plurality of boost circuits to boost the output of the charge pump during a fast start up. Afterwards, the boost circuits are disabled to allow the charge pump to generate high voltages without boosting. The boost circuits may be successively enabled to boost the voltage. The boost circuits may be loadless. The voltage regulator may operate in an open loop and may include a resistive divider as a reference voltage for regulating the high voltage from the charge pump. The charge pump may include spread spectrum pump clocking to reduce electromagnetic inference for capacitor or inductor on-chip charge pumping.

摘要翻译： 数字多电平存储器系统包括电荷泵和用于产生用于各种存储器操作的调节高电压的电压调节器。 电荷泵可以包括多个升压电路，以在快速启动期间升高电荷泵的输出。 之后，升压电路被禁止，使电荷泵产生高电压而不加速。 升压电路可以被连续地使能以升高电压。 升压电路可以是无负载的。 电压调节器可以在开环中工作，并且可以包括电阻分压器作为用于调节来自电荷泵的高电压的参考电压。 电荷泵可以包括扩频泵时钟，以减少用于电容器或电感器片上电荷泵浦的电磁推理。
